Embedded NetBSD on iMX233/OLinuXino
Petri Laakso has
worked to get NetBSD
going on the
iMX233/OLinuXino
ARM board, specifically the MAXI and MICRO boards. The port is stable enough to run multiuser and build software from pkgsrc. Supported hardware include
SD card,
GPIO,
USB host, and
a boot loader.

The hardware is ways below 50 EUR, so this is a good start to
get a nice and easy machine. More information on how to get things
running are available
in Petri's blog.
